Misbehavior of nodes in IoT based vehicular delay tolerant networks VDTNs

Various Internet of Things (IoT) applications are based and deployed on unstable wireless networks like the Delay Tolerant Network (DTN). But effective DTN data transmission seems to be an important concern for IoT applications. Vehicular Delay Tolerant Network (VDTN) is also one of the DTN application areas. Despite communication problems, VDTNs' consist of mobile devices that communicate wirelessly with one another to transmit data. This article highlights the issue of certain nodes that tend to disrupt a VDTN's connection. The case of nodes that interrupt the transmission of messages, which is an immensely challenging type of misconduct to recognize, is described in the article. We investigate the influence of this type of misconduct on nine VDTN routing algorithms using two different types of scenarios as well as a wide range of simulations. The outcomes indicate that focusing on the form of inappropriate behavior, duplication of messages, and smart selection of a next-hop can assist routing methods to be resistant to misconduct by nodes.

This article discusses the issue of effective DTN data transmission for IoT applications based on unstable wireless networks. It focuses on the case of nodes that disrupt VDTN connections and investigates their impact on nine VDTN routing algorithms. The outcomes indicate that considering the form of inappropriate behavior, message duplication, and smart selection of next-hop can enhance the resistance of routing methods to node misconduct.
